SPECIFICATION forming part of Letters Patent N0. 747,808, dated December 22, 1903.

` Application iled November 24, 1902. Serial No. 132.674. (No model.) I

To all whom t mayconcern:

Be it known that LJHENEY O. TRIPP,of Au burn, in the county of Cayuga, in the State of New York, haveinvented new and useful Im- -provements in Dump-Wagons, of which the following, taken in connection with the ac-- companying drawings, is a full, clear, and exact description. Y

This invention relates to improvements in dump-wagons in which the load is dumped centrally and longitudinally from the bottom of the box. l

One of the objects of this invention is to provide an open su pporting-frame with swinging` dump-box sections or walls which are pivotally suspended at their upper edges from the upper edges of the side walls of the sup- Verging planes to meet at their bottom edges for retaining the load.

Another Vobject is to provide a windingdrum and cable connections arranged so that both ends of the swinging walls are operated simultaneously.

A further Objectis to provide specific means for locking the bottom edges of the swinging walls in their closed position independently of the cable connections.'

ism therefor.

Referring to the drawings, Figure 1 is a side elevation of my improved dump-wagon, the wheels nearest to the point of view being removed. Figs. '2, 3, and 4 are sectional views taken, respectively, on lines 2 2, 3 3, and 4 4, Fig. 1. Fig. 5 is a top plan of the detached frame and boxseen in Figll. Fig. 6 is an enlarged'vertical plan of the meeting edges of the box-sections and the locking mechan- Fig. 7'is an end view of the parts seen in Fig. 6. Fig. 8 is a perspective view of the detached locking device and its operating-lever.

Similar reference characters indicate corresponding parts in all the views.v

and rear walls,and these extensions are united f by transverse bottom V.walls for forming suitable platforms Gand 7.A 'Y i The d ump-box properconsists of oppositelyarranged lengthwise sections or walls8 of substantially the same length as the distance between the end walls 3 andi4,'whic'h` form the f end walls of the dump-box, the upper edges of the sections 8 being hinged-at 9 to the upper edges ofthe sidey walls 5, and these sections incline downwardly and inwardly in converging planes and preferably meet at the bottom in a plane beneath the lower edges of the side walls 5 and together with the end walls 3 and 4 normally serve to retain the load. It is thus evident that thesections 8 swing laterally upon theirfhinges 9 to open and close the lower meeting edges, the side walls 5 serving as abutments to limit the out- War'd'swing of the sections 8, and when these sections are opened to their extreme limit a clear rectangular space may be formedof substantially the capacity of the inside of the main supporting-frame.

The means for controlling the operation of the sections 8 preferably consists of adruin 10, front andrear cables l1 12,and separate rotary shafts 13,7mounted upon and parallel with the sides `5, near the hinges 9. I preferably employ a pair of cables 11 and 12 for the opposite ends of each door, the inner upper ends of the cables 11 being secured to the opposite faces of the drum 10, andtheir lower ends are secured to suitable 'eyes 14, provided upon 'the adjacent ends of theswinging sections 8, while the intermediate portions of said cables 11 arerpa'ssed oversprocket-wheels 15 upon the forward ends of the shafts 13, and the lower ends of-,these cables 11 are engaged with idlers 16, mounted upon the front platformy in close proximity to each other and preferably closer together than the eyes 14, so that the draft of theflower ends of the cables is inwardly, and thereby tends to draw the meeting edges of the sections 8 into close engagement with each other.

The cables 12 at the rear. ends ofthe sec'-l rear platform and are attached to eyes 19,

which are secured to the lower rear ends of the sections 8, the relative arrangementof the idlers 18 and eyes 19 being similar to that described for the idlers 16 and eyes 14 for drawing the rear meeting ends of the sections 8 into close contact.

The drum 10 is preferably journaled upon the front wall with its axis parallel with and above the meeting edges of the swinging sections and is provided with a ratchet-wheel 20, which, together with the drum, is rotated by means of a pawl 21 and hand-lever 22, a suitable detent 23 being provided to engage the ratchet and hold the drum in its adjusted position.

It is evident from the foregoing description and accompanyingdrawings that the movement of the sections 8 is always under the control of the operator through the medium of the hand-lever 22 and cables 11 and l2 and that these sections may be open a slight distance for distributing the load evenly over the surface of the ground in any desired quantity, or they may be entirely opened, as shown by dotted lines in Fig 4, for discharging the load in bulk. V

The shafts 13, carrying the sprockets 15 and drums 17, are located in proximity to the upper edges and at the outside of the main supportingframe, so as not to interfere with the loading and unloading of the material.

In order to relieve the strain upon the cables and to insure a perfect closure of the lower meeting edges of the sections 8, I provide said lower edges with an additional locking mechanism, consisting of a rock-shaft 24, which is j ournaled in suitable lugs 25, provided upon one of the sections 8, said rockshaft being provided with loops 26, which swing into and out of engagement with lugs 27, provided upon the other section 8, so that when the loops are operatively engaged with 'the lugs 27 the meeting edges of the sections 8 are held in contact, and when the loops are rocked downwardly out of the path of the lugs 27 the sections are free to swing laterally and may then be controlled by the lever 22 and cables 11 and 12.

The means for rocking the shaft 24 preferably consists of a foot-lever 28, which is pivotally mounted upon the front platform in proximity to the seat 29, one arm of the lever being detachably engaged with a suitable shoulder 30, provided upon the front end of a rock-shaft, whereby as the foot-lever 28 is rocked the shaft is similarly rocked and the loops 26 are moved into and out of engagement with the lugs 27. It will be noted that the rock-shaft 24 and loops 26 and also lugs 27 swing with their respective sections 8, to which they are attached, and therefore leave a clear open space for the discharge of the material when the sections are open.

I do not limit myself to hinging the dumping-sections to the upper edges of the side walls, as it will be evident that they may be hinged at some distance from the upper edges Vention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a dump-wagon, the combination of a supporting-frame, swinging bottom sections hinged at their upper edges and inclining downwardly and inwardly therefrom and meeting at their lower edges, separate shafts at opposite sides of and parallel with the swinging bottom sections and a revoluble drum substantially midway between the front ends of the shafts and having its axis parallel therewith, means to rotate the drum, sprocket-wheels on the front ends of the shafts, and separate cables passed over said sprocket-wheels and having their upper ends attached to the drum and their lower ends attached to the front ends of the swinging sections.

2. In a dump-wagon, the combination of opposite sides and vends of a supporting-frame, swinging box-sections hinged to the upper edges of the sides and inclining downwardly and inward-ly therefrom and meeting at their lower edges, revoluble shafts mounted on the upper edges of the side walls parallel to the swinging axes of the bottom sections, idlers mounted on the frame at the front and rear endsIof the s winging sections, separate cables connected to the front ends of the shafts and having their lower ends passed over the front idlers and connected to the front ends of the bottom sections, a drum for winding and unwinding said cables, means for rotating the drum, and additional cables connecting the rear ends of the shafts to the rear ends of the swinging sections.

3. In a dump-wagon, a supporting-frame, swinging bottom sections hinged to the supporting-frame and inclining downwardly and inwardly therefrom to meet at their lower edges, opposite revoluble shafts mounted on the frame parallel with the swinging axes of the sections, a rotary drum operatively connected to rotate said shafts simultaneously, and connections between said shafts and swinging sections to transmit motion from the former to the latter and means for operating the drum.

4. In a dump-wagon, the combination with a supportingframe having side walls, of dumping-sections hinged to the upper edges of the side walls and extending downwardly and inwardly and meeting at theirlower edges, rotary shafts mounted upon the supportingframe, parallel with and in proximity to the swinging axes of said sections, separate cables connected to the opposite ends of the shafts and to the opposite ends of said swinging sections and means for rotating the shafts simultaneously.
